我有一个Android应用程序，当我在两个活动之间切换时，我想要应用3D过渡...我知道方法overridePendingTransition()但它没有任何3D动画..那么如何做到这一点？

我曾经在活动之间使用过3D Cubic Transition.Credit是Robert Heim，他是该计划的开发人员。

Here is extension of @Vipul Shah code with reverse animation functionality
add following method in to "ActivitySwitcher"
public static void animationInReverse(View container, WindowManager windowManager) {
animationInReverse(container, windowManager, null);
}
public static void animationInReverse(View container, WindowManager windowManager, AnimationFinishedListener listener) {
apply3DRotation(-90, 0, false, container, windowManager, listener);
}
public static void animationOutReverse(View container, WindowManager windowManager) {
animationOut(container, windowManager, null);
}
public static void animationOutReverse(View container, WindowManager windowManager, AnimationFinishedListener listener) {
apply3DRotation(0, 90, true, container, windowManager, listener);
}
and add this to first activity
@Override
protected void onResume() {
if (isFromOncreate) {
isFromOncreate = false;
ActivitySwitcher.animationIn(findViewById(R.id.container), getWindowManager());
} else {
ActivitySwitcher.animationInReverse(findViewById(R.id.container), getWindowManager());
}
super.onResume();
}
